拖放问题jQuery [英] drag and drop issue jquery

问题描述

我有以下使用脚本的代码，这些脚本使东西可拖放.目前，我有两段可拖动内容，如果可以的话，可以将其放在两个位置，如果正确，则系统将更改并说正确，我想知道是否还有我可以创建HTML div并运行代码通过并将可拖动对象与可拖放对象匹配.我的人员具有非技术背景，具有基本的HTML知识，所以您现在如何添加div并将其删除，但是他们能够处理脚本，我想知道，如果我的ID为1-10可拖动的内容与可放置的1-10的内容相同，因此只能将ID 1可拖动的ID添加到ID 1的可放置的ID.

I have the code below using the script i am making stuff draggable and droppable. currently i have two pieces for draggable content, and two place they can be dropped if correct then the system will change and say correct, I would like to know if there is away that i would be able just create the HTML divs and the code runs through and matches the draggable to the dropable. I have people that have a non-technical backdround, have basic HTML knowledge so thy now how to add divs and remove them but they are able to deal with script, i would like to know, if i had ID of 1-10 for the draggable content and the same for the dropable 1-10 so id 1 draggable can only be added to id one droppable.

推荐答案

您将需要避免使用HTML id并开始使用类.以下是使用工作示例的方法:

You will need to avoid using HTML id for this and start using classes. Here is how to do that, with a working example:

您的HTML:

<div id="draggable_2" class="ui-widget-content draggable-item">
    <p>draggable_2</p>
</div>
<div id="draggable" class="ui-widget-content draggable-item">
    <p>draggable</p>
</div>
<div class="ui-widget-header droppable-item" data-accept="#draggable">
    <p></p>
</div>
<div class="ui-widget-header droppable-item" data-accept="#draggable_2">
    <p></p>
</div>
<div class="ui-widget-header droppable-item" data-accept="#draggable_3">
    <p></p>
</div>

您的JavaScript:

Your javascript:

$(function () {
    $(".draggable-item").draggable();

    $('.droppable-item').each(function (i, ele) {
        // Gets the accepted from the HTML property "data-accept"
        var accept = $(this).data('accept');

        // This is just to show what the item accepts. you can remove it.
        $(this).find('p').text('accepts: ' + accept);

        // Init the jQuery UI droppable()
        $(this).droppable({
            accept: accept,
            drop: function (event, ui) {
                $(this)
                    .removeClass("ui-widget-header")
                    .addClass("ui-state-highlight")
                    .find("p")
                    .html("Dropped!");
            },
            out: function (event, ui) {
                $(this).removeClass("ui-state-highlight").addClass("ui-widget-header")
                    .find("p")
                .html("accept: " + accept);
            }
        });
    });
});
